SKID.

Specification of Letters Patent.

Patented Nov. 29, 1910.

Application filed November 11, 1909; Serial No. 527,522.

To all whom it may concern:

Be it known that I, AUGUST LEMKE, a citizen of the United States of America, residin at Detroit, in the county of Wayne and gtate of Michigan, have invented certain new and useful Improvements in Skids, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to skids and consists in the'peculiar construction of the skid, and, further, in the novel construction, combinationand arrangement of parts as more fully hereinafter described.

In the drawings-Figure 1 is a side elevation of my invention as applied to a wagon; Fig. 2 is a longitudinal section through the upper section of the skid; Fig. 3 is a top plan view of the lower section of the skid;

and FigsA: and 5 are sectional perspective views illustrating certain parts of my invention.

A represents the skid, comprising a stationary section B and a movable section or skid proper, C, and D is mechanism for raising and lowering the latter. The movable section comprises the longitudinal side membersB the cross-bars or rods C and the hooks D for engaging the pivot rod E of the wagon end gate F, while the stationary section consists of complementary members H, each having one end recessedas at -I to engage the axle J of a wagon, and provided at the other end with an enlarged bearing portion K. p

The shaft L for raising and lowering the mechanism is rotatively journaled in bearings M in the portion K, and has its opposite ends projecting beyond said bearing portions. Upon each of the rojecting ends of the shaft L a gear wheel is fixedly secured, while loosely journaled' thereon is a guide bearin O. This guide bearin is preferably forme from a single sheet 0 metal bent to form members a 72 positioned upon thev opposite sides of the gear wheel N, .and spaced apart at their lower edges by the connected portions 0, and at their upper edges by rollers P loosely journaled upon .pins 11.

e is an aperture in the lower portion of said member, through which the gear wheel N pro'ects, and f is a' bracket upon each of the si e members B to which a segment Q pivoted, as by means of the cotter pin The se ents Q are held in driving engagement with the gear wheels'N v.ing

operating lever, such as a foot-lever-A,

by the bearings O, and'since the said hearing members are loosely sleeved upon the shaft L they readily adjust themselves to the different angular relations of the segments Q. r

The shaft L may be rotated in an desirable manner, but I referably emp 0y a lever bearing R secured to each of the projectin space apertures h with which a crow-bar, or other lever, may be engaged.

ends of the shaft L, and having- In order to prevent backward rotation of l the shaft L during the lifting of the skid, a ratchet mechanism is employed,.which,- as shown, preferably comprises a pair of ratchet wheels S rigidlysecured to the shaft L, and gravity pawls T adaptedto engage the wheels S. The pawls T are rigidly se-. cured to a shaft U, which is journaled in bearingsu in the members H, and V are hand-levers carried by the opposite ends of said shaft, whereby the pawls may be thrown out of engagement with the ratchet wheels.

To aid in lowering the skid, I pro'vid'ea clutch mechanism, which may be of any suitable form, the construction shown c'om-' prising a drum W fixed to the shaft L and a brake band X. I

Y is an operating shaft for the'brake provided with a rocker Z intermediate its ends for actuating the brake band, and having its 0 posite ends journaled in and projecteyond the bearing portions K. An

secured to each of the projecting ends of this shaft. B is an angle-shaped member loosely sleeved upon a shaft C extending transversely and at the lower end of movable section, or skid proper. The portion D of this member, when the parts are 1n the relation shown in Fig. 1, form anextension of the skid proper, u on which the barrels or other articles to e loaded are rolled, while the ortion E forms an abutment against which the articles strike as they are loaded upon the movable sectiontoforce the angle-shaped member into its retaining portion, as shown in Fig. 2. I preferably provide means for automatically lockin the member B in itsretainin position. as shown, F- is a do fixed upon a' shaft G loosely-journaled in arings H in the side members of the movable. section. This dog is yieldingly held by a sprin J against a stop K so as to be m the pat of the memthe path of the V is rocked into its retaining the member E elow the head has passed of the dog the" spring forces the latter into locking enga ement with a slot N".

In or1 der to rovi e means for releasing the dog, theen s of the shaft G are extended beyond the side members of the skid proper and bent positioned in .to form operating handles, or

levers I. If desired, a pair of lockin 'dogs could be positioned upon the shaft a, as will be readily understood. The lower end of themovable section is preferably provided with rollers U, loosely journaled upon the ends of the shaft C of the angle-shaped member.

In the operation of the parts, assumin that a heavybarrel or keg is' to be loade into the wagon'or truck, the parts are positioned as shown in full lines in Fig. 1. The barrel is then rolled up the portion 1 until it engages the movable section, when a further movement will force the retaining memher into the position shown in-Fig. 2. The operator thenrotates the shaft L, which drives the segments Q forward, raising the skid proper to the position shown in dotted lines, and the barrel can then be easily rolled into the vwagon. To lower'the movable section, the operator applies the brake by means of the foot-lever A, and releases the ratchet mechanism through the medium of the hand-lever V whereupon the movable section can be. grad ually lowered. In the loading of heavy boxes, considerable difiiculty is also in removing after the movable section has been raised. I

of rollers O jo-urnaled in a member P which is positioned between the sides of the section 0, and adapted to be raised above or a-plane below the top of said sides. To accomplish this raising and lowering operation, bayonet slots Q are formed in the sides of; the movable section with which the shafts gage, and in order to hold the member P In its I raised or lowered position, apertures S S are formed in the sides of the latter, whichv register with apertures S in the sides of the sk1d proper respectively in the raised and lowered position of the member P. T

are pins adapted to beinserted terin a ertures. The skid propermay be deta'c e from the stationary section B by withdrawing the'segments Q from the guide bearin O, or byfldetaching said segments from t e brackets f.

While I have shown my to a' wagon, it will be in said regisdevice' as applied readily understood although' I have described the ratchet shaft L.

frequently experienced in placing the boxes onthe movable section and the boxes from the latter connected thereto,

R of the member P en-- that it is a inary skid is employed. Also, brake and raising mechanisms as provided each with a pair of'operating levers, if desirable the actuating levers upon one side of the skid might be dispensed with. In certain uses for which the skid is employed, it is preferable, instead of rotating the shaft L by hand to drive the same by a motor and to this end a sprocket V is fixed upon the W .is a drive chain for the sprocket V leading to any suitable source of power, such as the drive shaft of a motor truck (not shown).
